Filed: 1972-03-24
Abstract: 1341943 Combustion air heater DAIMLERBENZ AG 24 March 1972 [27 March 1971] 13897/72 Heading F1B A method of operating an air-compressing, compression-ignition, injection type multi-fuel I.C. engine, wherein a flame heater for heating the induced air is automatically put into operation when the engine is running under load with a fuel which is not readily ignitable, by means responsive to a quantity serving as a measure of the ignitability of the engine fuel. An engine for operating by the above method includes a fuel injection pump 2 supplied by pipe 4 from tank 3. Combustion air is fed to an induction pipe 6 by an exhaust-gas driven turbocharger 5. A flame air-heater 7 is provided at the entry to the induction pipe and is fed with the same fuel as the engine by a pump drawing fuel through a branch line 8 from the main fuel pipe 4. Operation of the heater is controlled by a device 9 which receives signals from unit 10 which measures the density of the fuel and from a unit 11 which indicates the instantaneous position of the control rod of the fuel injection pump 2. When a fuel which is difficult to ignite e.g. petrol, is detected by the unit 10, the burner is started and continues to operate until the unit 11 detects that the engine is running in a load range in which the fuel will continue to burn. In pistons in which the combustion chamber is formed by a bowl in the piston, an annular groove may be formed in the piston to reduce heat flow from the piston to the cylinder walls and thus raise the piston temperature.

Inventor: MICKLETHWAIT ERIC WALTER
IPC: H01M8/04
Filed: 1964-04-06
Abstract: 1,105,137. Fuel cells. CHLORIDE OVERSEAS Ltd. 5 April, 1965 [6 April, 1964 (2)], Nos. 14192/64 and 13961/65. Heading H1B. In a fuel cell in which one of the reactants is a gas supplied under pressure; the gas is also employed to feed liquid through the cell. In the arrangement shown a cylinder 16 of oxygen supplies oxidant to the battery 10 and inflates one of the bellows 15a or 15b in tanks 11a and 11b respectively to displace the liquid from one tank through the battery to the other. At the beginning of a working cycle a charge of fuel and concentrated electrolyte is introduced into the empty tank 11a or 11b from a replaceable capsule 14, and the liquid in the full tank is agitated by the oxygen supply 16 via pipe 21a or 21b. At the same time the tanks and bellows are vented to the atmosphere. To run the plant a four-pole valve 30 is moved to the run position so that one of the bellows is inflated and drives the liquid through the battery to the other tank. Towards the end of the working cycle the pre-charged tank overflows, owing to the addition of the initial charge, and this results in the elimination of the water produced in the cell. For the next cycle of operations the other bellows is inflated and to ensure unidirectional flow through the battery a changeover valve 20 is operated to reverse the connections between the tanks and battery In Fig. 2 (not shown) a gas lift pump raises electrolyte from a lower reservoir to an upper reservoir whence it flows through the battery back to the lower reservoir. The gas may be oxygen and after raising the electrolyte it may be fed to the battery. Gas-operated reciprocating pumps may also be used.
